MRI

MRI is one of the most significant advances in medical imaging. It allows physicians to see inside the human body with remarkable detail.

MRI does not use X-rays to create images. Instead, it combines magnetic fields with radiowaves and uses specially designed computers to produce detailed images of internal body structures. While X-rays may be best for showing bones, physicians use MRI to examine "soft" tissue such as muscle, nerves, cartilage, ligaments, tendons, vertebral discs, and various internal organs.

What to Expect

The technologist will escort you to the MRI suite where you will be asked a series of screening questions prior to the MRI exam. Although MRI is an advanced imaging technique, the exam itself is relatively easy and comfortable. You will be asked to lie on a cushioned table. A device called an imaging coil will be placed over or under you. When you are comfortably positioned, the table will move into the open magnet.

From the control area, the technologist will stay in constant contact with you, both visually and through an intercom. You will be asked to remain still while images are obtained. As the exam begins you will hear a variety of muffled thumping or clicking sounds. These sounds are normal and should not be cause for concern. Other than the muted sounds, MRI usually produces no bodily sensations.

Depending on your study, the technologist or nurse may place an intravenous (IV) line through which a MRI contrast agent will be given.

Most MRI exams last between 30 to 60 minutes.

Preparation

You will be asked to change into a hospital gown. Make-up and hairsprays should also be avoided. Before your test, you will be asked to remove all metallic objects, such as eyeglasses, jewelry, wristwatches, etc.

Please advise the technologist if you have any of the following:

Cardiac pacemakers, defibrillators or other implanted devices.
Aneurysm clips or previous brain surgery
Metal shavings or rust in the eye
Metal fragments from military service or work
Surgical implantation of any metal, wire, or electronic devices.
Artificial cardiac valves
Pregnancy
Any recent surgery

Depending on the type of exam, you may receive an injection of contrast material. If you are allergic to any medications, are diabetic, or have renal disease, please tell your doctor, the radiologist or the technologist.

Open MRI

MRI does not use X-rays to create images. Instead, it combines magnetic fields with radiowaves and uses specially designed computers to produce detailed images of internal body structures. While X-rays may be best for showing bones, doctors use MRI to examine "soft" tissue such as muscle, nerves, cartilage, ligaments, tendons, vertebral discs, and various internal organs.

Specialized MRI unit with a wide-open design to accommodate patients with athletic or large body types, and to alleviate anxious or claustrophobic patient due to its unobtrusive open design.

Open MRI is provided at our Horseshoe Pond and CIC Pillsbury offices.

Preparation

If you are having an MRI or MRA of the abdomen or pelvis, please abstain from food and drink for up to 8 hours prior to your study. There are food restrictions for some MRI studies.
